Antibody for West Nile virus shows promise

Researchers have developed an antibody that can cure mice of West Nile virus (WNV) infection, a disease for which no specific treatment exists, the National Institute of Allergy and Infectious Diseases (NIAID) has announced.

Maxim Pharmaceuticals issued patent for method of identifying therapeutically effective immunosupressive agents

Maxim Pharmaceuticals have announced the United States Patent and Trademark Office issued U.S. patent number 6,828,091 B2, entitled "Method of Identifying Immunosuppressive Agents."

As syphilis rates increase in Los Angeles County, new study suggests the disease is increasing HIV rates

The syphilis epidemic among men who have sex with men in Los Angeles County may be contributing to rates of HIV in this population, according to a new report published in the Journal of Acquired Immune Deficiency Syndrome.

How Ebola virus infects cells - discovery

Ebola virus reproduction in laboratory-grown cells is severely hampered by enzyme-inhibiting chemicals, and these chemicals deserve further study as possible treatments for Ebola virus infections in humans, report scientists supported in part by the National Institute of Allergy and Infectious Diseases (NIAID).

Outbreak of Legionnaires' disease at New York hospital

After four patients contracted Legionnaires' disease at New York-Presbyterian Hospital, the state Health Department says appropriate steps have been taken to safeguard patients and staff from an outbreak of the disease.

Scientists weaponize an antibody to deliver continuous attacks on cancer cells

In a recent study published in Molecular Cancer Therapeutics, researchers at the Weizmann Institute of Science paired the active ingredient of a garden remedy with advanced bio-technology to deliver a powerful punch against cancer. The cancer killing effectiveness lies in their technique of arming a cancer-targeting antibody with the destructive potential of the dietary molecule otherwise known as "allicin."

New strategy to identify differences between non-metastatic and highly metastatic breast cancer cells

Researchers at the University of California, San Diego have used a new strategy to identify differences between non-metastatic and highly metastatic breast cancer cells. The article by Valerie Montel et al., "Expression profiling of primary tumors and matched lymphatic and lung metastases in a xenogeneic breast cancer model," appears in the May 2005 issue of The American Journal of Pathology and is accompanied by a commentary.

Discovery may lead to new drugs to prevent sexually transmitted HIV infection

Scientists have long suspected that HIV hijacks immune cells called dendritic cells to infiltrate the immune system. Now UCLA AIDS Institute researchers have shown that blocking HIV's access to a naturally occurring molecule on dendritic cells may cut their ability to smuggle the virus into other immune cells.

With a complement, the sperm gets the egg

When a sperm fuses with an egg, a specific reaction takes place that exposes the inner membrane of the spermatozoa, where a protein called the complement regulator membrane cofactor protein (MCP) is expressed. MCP is an immune regulatory molecule and its presence in reproductive tissues was unclear.

It will be at least a decade before a malaria vaccine is available

A seminar on malaria in this week’s issue of The Lancet states that it will be at least a decade before a vaccine for the disease will be ready for widespread use and emphasises the need to expand the use of existing control methods.

Clinical study of MDX-010/MDX-1379 combination shows durable responses in patients with metastatic melanoma

Medarex, Inc. and Bristol-Myers Squibb Company announced today that complete or partial responses in seven of 56 patients with metastatic melanoma showed durability ranging from four months to the longest still ongoing at over 34 months, with five of the seven responses ongoing for more than two years.

RNA interference permanently silences key breast cancer gene

In laboratory mouse experiments, researchers at The University of Texas M. D. Anderson Cancer Center have developed a way to use RNA interference (RNAi) so that it permanently hampers breast cancer development. The technique permanently silences activated STAT3, a crucial gene found in some human breast tumors, thus reducing the cancer's ability to become invasive.

Arthritis medications (methotrexate and leflunomide) commonly used in adults are safe and effective in children

An international team of researchers, led by Dr. Earl Silverman of The Hospital for Sick Children (Sick Kids), has found that two arthritis medications (methotrexate and leflunomide) commonly used in adults are safe and effective in children. This research is reported in the April 21, 2005 issue of The New England Journal of Medicine.

Red light cameras can reduce crash-related injuries

Red-light cameras can reduce the number of injuries from car crashes at intersections by up to 30 percent, according to a new worldwide review of studies.

New method for the study of ion channel gating kinetics

An ion channel is a protein pore that lets ions (charged atoms such as calcium) pass through a cell's membrane. The method fits data to a new class of models, called manifest interconductance rank (MIR) models, which will give researchers a better understanding of the mechanisms by which ion channels open and close.

Children on school buses may face increased exposure to diesel pollution

Diesel particle pollution inside urban school buses may be worse than levels found in the surrounding roadway air, according to a study by scientists at the University of California. The report appears in the April 15 issue of the American Chemical Society's journal Environmental Science & Technology.

Allergic diseases have increased

The rate of allergic diseases (atopy) in adults has steadily increased over the last quarter of the 20th century, but the reason for the increase is still unknown, according to a study published online by the BMJ.

Key discovery about non-Hodgkin lymphoma

There is a surprise benefit to being either an only child, the oldest sibling or even enduring some allergies – you are significantly less likely to develop non-Hodgkin lymphoma (NHL), according to new research from the University of New South Wales (UNSW).
